摘要

Sea clutter suppression is critical in the detection of low-velocity targets using a passive bistatic radar. The residual sea clutter may become high when the normalized least-mean-square (NLMS) algorithm with a small step size is used for this purpose. While a large step size can be used to reduce the residual sea clutter, it yields a widened filter notch, and thereby, causes significant target signal energy loss. A multi-channel NLMS algorithm is proposed to solve this problem, and its effectiveness is verified by simulation and real radar data analysis.
